Filter by:This study aims to analyze outcomes of patients with systemic right ventricle (SRV) implanted with Cardiac Resynchronization Therapy (CRT) systems and to compare the impact of CRT in SRV patients with other congenital heart diseases (CHD).
The aim of the study is to evaluate the effects of intermittent hypoxic-hyperoxic training (IHHT) to protect myocardium against perioperative myocardial injury during cardiac surgery using cardiopulmonary bypass.
There is existing data in the literature that suggests an additional predictive value of three dimensional ECG with respect to the presence of electrical abnormalities and for an existing cardiac disease. Especially regarding patients who suffered from a myocardial infarction in the past (post MI patients), evidence has been provided for a potential association of 3D repolarisation abnormalities and incidence of sudden cardiac death (SCD). In addition, there is some vague evidence of so called 3D ECG and prediction of coronary artery disease. This 3D ECG device is using the technology of 3D ECG vector loops and is assessing the variability of these ECG vector loops in the 3-dimensional space. Based on these data, the parameters of 3D ECG are suggested to carry certain value to predict or to identify individuals already suffering from a cardiac disease or being at risk experiencing a cardiac event in the future. In this context we performed a preliminary study with 3D-ECG device in healthy volunteers evaluating the robustness of this method with respect to reproducibility, intra- and intra-observer variability which could be confirmed. We thus postulate that the 3D ECG technology might bear the potential to serve as a sufficient screening method for diagnosing cardiomyopathy in patients with an unknown heart failure etiology.
Transthyretin (TTR) amyloidosis is a rare disabling disorder that can be hereditary or sporadic. Depending on the form, various tissues are affected. While in hereditary cases, neuropathy is predominant, cardiac impairment is the main manifestation in the sporadic form. The main objective of this project is to evaluate the proportion of patients with neuropathy in a population of patients with a non-mutated TTR amyloid cardiopathy condition.
Prospective US registry of pregnant women with cardiac disease to address the substantial gaps in knowledge surrounding these patients, in order to improve future care.
The investigators evaluate the effects of intracoronary and intravenous administration of nicorandil on cardiac sympathetic nerve activity and distribution in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention
Neurally adjusted ventilatory assist (NAVA) is a new mode of mechanical ventilation that delivers ventilatory assist in proportion to neural effort. The investigators hope to compare the hemodynamic and pulmonary effect in children after surgical repair of congenital heart disease with right ventricular hypertrophic ventilated with Pressure control ventilation (PCV), Pressure support ventilation (PSV), and NAVA by a crossover study.
SOCRATES is part of Boston Scientific's (BSC) Post-market surveillance system. The implementation of such systems is mandatory per local regulations such as the Regulation '(EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices' or short Medical Device Regulation (MDR). The SOCRATES design is therefore based on the BSC's commitment as well as external regulatory requirements to proactively and systematically gather, record and analyze relevant data on the quality, performance and safety of devices throughout their entire lifetime.
SETANTA study will investigate the incidence of cardiac abnormalities as assessed by cardiac magnetic resonance imaging in unselected patients after acute SARS-CoV-2 infection and correlation with immunological response and biomarkers of coagulation.
With an incidence of 0.8 %, congenital heart disease (CHD) is the leading cause of congenital anomalies at birth. Medical advances in CHD have transferred the mortality from childhood to adulthood and today there are more adults with CHD than children. After focusing on survival, more attention is being given to health-related quality of life and secondary prevention in this population where warning signals are launched on the risk of sedentary lifestyle, obesity, cardiovascular risk 1. The cardiopulmonary exercise test (CPET), which is a non-invasive and dynamic examination, is becoming the gold standard to the follow-up 2 of these patients by allowing to quantify disease severity, to evaluate the quality of life 3, to give important prognostic information on functional capacity and haemodynamic response 4, to facilitate a safe decision-making when prescribing exercise programmes and sport participation for these children with CHD 5. In this context, in a cross-sectional study from 2010 to 2015, the investigators evaluated the cardiopulmonary fitness of children with CHD by comparing them with healthy children 6. In this study, 496 children with CHD compared to 302 healthy children were included. It showed that maximum oxygen uptake (VO2max) and ventilatory anaerobic threshold (VAT) are decreased in CHD children compared to healthy children, clinical determinants of decreased VO2max have been defined for CHD children. This study was proposed, despite the cross-sectional nature, an average decrease in annual VO2max (0,84 ml/kg/min per year) to make pediatric and congenital cardiologist aware of the need to a regular follow up for these patients. In this new study, the main objective was to know the real evolution of VO2max in these patients from this same cohort, with a longitudinal design, by collecting a new CPET carried out between 2015 and 2020 and compared these results to healthy pediatric population. The secondary objectives were: to know the evolution of the VAT, to define the clinical determinants in relation to the annual decrease of the VO2max. And to describe the population lost to follow-up in this retrospective study which represents current practice.
